Abstract (en)
[origin: WO2014126478A1] Method for cutting of at least one line (38, 40, 42, 44) disposed along a pipe string (16) in a well (2), comprising: (A) using a cutting tool (48) for selective cutting activation and provided with at least one cut-forming means (54, 56, 58, 60) for cutting in a radial direction outward from the cutting tool (48); and (B) lowering the cutting tool (48) to a longitudinal section (L1) where the cutting is to be carried out. The distinctive characteristic is that of using, in step (A), a cutting tool (48) for controlled cutting, by means of said means (54, 56, 58, 60), in a peripheral direction and distributed in an axial direction relative to the cutting tool (48); and (C) activating the cutting tool (48) and cutting, in the radial direction through and past the wall of the pipe string (16), at least one peripherally extending hole (62, 64, 66, 68) collectively covering the entire circumference of the pipe string (16), and also distributing the hole (62, 64, 66, 68) in the axial direction.
